TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHRISTIAN HoLMEs, of Washington, in the county of' Fayette, and State of Ohio, have invented a new and improved LiftingJack; and I do hereby declare that the following is a full, clear, and enact description of the same, which will enable othersvskilled in the art to make and use my invention, reference being had to the accompanying drawings which form part of this specication.

The present invention relates to u lifting-jack for wagon and carriage-axles, which is so constructed as to be self-sustaining when placed under the wagon-axle, asl the fulcrum is placed out of the line of bearing or gravitation, which is within the centre of the base. The base to the jack is pivoted to the stand, and thus a. broader base is admitted, consequently producing a. bettei` support on soft ground, as well as being maintained in a better position for raising the weight through the axle underneath which the jack is placed. In the accompanying plate of drawings my improved lifting-jack is illustrated- Figure 1-being a-side elevation of the same, and

Figure 2 an edge view of the standard and hase. v

A, in the drawings, represents the base to the jack, to whichV is pivoted or hinged the lever end of ythe standard B, carryingat its upper end, by a fulcium-pin, C, the lifting-arm or lever D, through which the axle rf" is raised when placed under-'the same. The fulcrum to the liftinglever is out ofthe line with 'the weight or bearing thereon, while the line of bearing is always in the centre of the base, and as the base is hinged to the stand or base, a broad buse can, be used, the advantages of which are obvious.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- A lifting-jack, composed of a lifting-lever, hung to a stundarrhhaving baise-board, substantially as and for the purpose described.

The above specification of my invention signed by me this 13th day of July, 1867.
